/* =========================================================================
   Virelo — styles.css (landing gestao-virelo.com.br)
   Design system da Virelo: fundo claro e quente (paper), seções escuras
   (ink) nos momentos de chamada, tipografia grande, acento cobre aplicado
   com moderação. A identidade é deliberadamente plana: sem gradiente de
   marca e sem brilho 3D, coerente com o símbolo dos dois elos.
   Mobile-first: estilos base = mobile, breakpoints via min-width.
   Tokens idênticos aos do sistema (renderiza-web/projects/design/tokens.css).
